What it is

A desktop GUI for running open models locally on Mac, Windows and Linux, built on llama.cpp and MLX. It includes a model browser, chat UI and a local OpenAI-compatible server, plus an lms CLI and Python and TypeScript SDKs for wiring apps to it.

Why it earns a slot

The friendly version of local inference — it tells you which quantisation fits your RAM before you download 40GB. Good for comparing open models side by side, then serving the winner to your app on localhost.

Know before you commit

GUI-first design makes it awkward to run headless on a server — use Ollama or vLLM for that. Commercial use inside a company may require the separate enterprise licence.
